The application of parking management system has certain characteristics

Parking Management System Features:
(1) Penetration: It can penetrate any metal car explosion-proof membrane, and it can be placed in the car from a long-distance card, without shaking the window to automatically identify the induction;
(2) Directionality: Infrared positioning radio transmission dual channel mode of operation, with strict directionality and stability, never read card at 60 degrees outside the reader area.
(3) Stability: A variety of environmental sensing technologies are applied to make it possible to automatically adjust signal parameters according to the needs of the environment.
(4) Adaptability: The card reader has a variety of working modes, and the corresponding working mode can be selected according to the application environment, such as: outdoor working mode (applicable to open parking lot and ETC system), indoor working mode (applicable to underground parking lot) Wait.
(5) Anti-jamming: This reader integrates the technology of body code setting, multi-technology, code division multiple access and other technologies with good anti-interference (even if the two readers are close together, as long as the infrared area is not superimposed It will not cause interference.)
(6) Environmental protection: Card readers and electronic tags have no electromagnetic radiation when they are not read, so they will not cause any harm to the human body.
(7) Cold resistance: When operating in severe cold weather, readers use infrared to automatically warm up, and the card reading signal is not attenuated by climate change.
(8) Compatibility: The card reader has a variety of data transmission formats and is fully compatible with existing domestic controller systems.
(9)Maintenance: It is a pure industrial grade manufacturing with super strong lightning protection function. Each level of the circuit has a protective function. It works all day without maintenance.
Due to the particularity of the application of the parking lot management system, not all long-distance card reading devices can perform their functions. In practical applications, the signal can penetrate the car's thermal insulation film, signal interference in the adjacent lanes, and Vehicle signal interference, microwave radiation hazard, signal attenuation, electromagnetic compatibility and other key technologies have become an important factor in product stability.
Parking Management System Principle
This long-range directional reader combines the features of infrared and radio frequency communication and complements the working advantages of two different frequency channels to communicate information with each other. RF is a non-directional electromagnetic wave, it is difficult to accurately orientation, but the communication speed is fast; while infrared has a strict angle positioning, but the communication speed is slow; in a practical application of parking lot, it is difficult to achieve a desired use of a certain channel communication.
Principle: The reader emits a 60-degree infrared scanning signal. The infrared signal is encrypted data, including wake-up coding and machine coding information. When the long-distance card in hibernation enters the infrared signal range sent by the card reader, it is immediately awakened. Work, launch RF electromagnetic wave to send long-distance card code, while sending the card code, also send the card reader machine code to the card reader; the card reader will verify the machine code after receiving the card number, and the machine The match of the code is valid. The card is directly uploaded to the host computer. The direct deletion of the machine code is inconsistent with the machine code, which avoids the serial number interference of the adjacent lane and the following car.
